Abstract
A 10-channel automatic data acquisition system has been designed and environmentally packaged for use with underground strain-gage applications and associated instruments. The system uses commercially available components and is assembled in two plastic enclosures. Environmental control is provided through a specially designed (compressed-air) air-conditioning system and water- resistant cabling. Accuracies of 0.01 pct and resolution of 1 uv have been obtained in underground tests.
